ARMv8/v9-GIC Virtual Interrupt Direct Injection Routing Mechanism (Doorbell)

ver0.1 Introduction The previous article introduced the system architecture for directly injecting virtual interrupts into VMs under the GIC framework. We detailed the background of directly injecting interrupts into VMs and how to remap MSI into virtual interrupts for reinjection into vPE with the support of GIC hardware. Of course, this process also requires assistance … Read more
